When testing diffusion over a selectively permeable membrane, the proper setup is aimed at putting different concentrations into tubes and the same water volume.
<h3>What is a selectively permeable membrane?</h3>
A selectively permeable membrane is a physical barrier that allows the passage of certain substances but not others.
The cell membrane is a selectively permeable membrane that cells need to interchange nutrients and waste with their environment.
In conclusion, a suitable experiment to show the process of diffusion in a selectively permeable membrane is to put concentrations of the solute into tubes and the same volume of solvent (water).

Answer:
✨Chemicals in the air create too much oxygen.✨
Explanation:
✨ plant-like algae bloom in polluted waters and create oxygen-depleted dead zones.✨
✨Water pollution that alters a plant’s surrounding pH level, such as acid rain, can harm or kill the plant. Acid rain forms because of atmospheric sulfur dioxide and nitrogen dioxide, which are emitted from natural and human-made sources. These include volcanic activity and burning fossil fuels.✨
